This page is not medical advice or a rehabilitation protocol. Ely's personal review applies to purchased workout plans and does not replace an in-person assessment by a licensed healthcare professional.
Terminal knee extension (TKE) specifically targets the vastus medialis oblique (VMO), the teardrop-shaped muscle on the inner knee. VMO weakness contributes to patellofemoral issues and knee instability—TKEs help correct this imbalance.
When to use it
Use Terminal Knee Extension only for general fitness when you can perform it comfortably. For pain, injury, surgery, or a medical condition, follow a licensed healthcare professional's instructions instead.
Who it's for
Those with patellofemoral issues or knee instability.
Set up with a resistance band behind your knee. Start with a slight knee bend and straighten fully against the band's resistance. Focus on achieving complete lockout and feeling the VMO contract.

Anchor band behind knee at low position.
Stand facing anchor with band around back of knee.
Start with knee slightly bent.
Straighten knee against band resistance.
Hold full extension briefly.
Return to slight bend and repeat.
Targets VMO for knee stability.
Great for patellofemoral issues.
Focus on full extension.
For general fitness, start Terminal Knee Extension with 1-2 light, controlled sets and increase only when the movement remains comfortable. This is not rehabilitation dosage; use the frequency and progression given by your licensed healthcare professional for an injury or surgery.
Not reaching full extension at the top of the movement.
Cutting the range of motion short on the Terminal Knee Extension can reduce the training stimulus for your Vastus medialis oblique. Use the largest comfortable range you can control without changing the intended setup.
Moving too fast and losing control of the movement.
Rushing through the Terminal Knee Extension makes it easier to lose position and harder to keep tension on your Vastus medialis oblique. Slow down enough to control both the lifting and lowering portions of each rep.
Using too heavy band.
Loading more weight than you can control on the Terminal Knee Extension often creates compensations that shift work away from your Vastus medialis oblique. Reduce the load until each rep follows the intended path.
Those with patellofemoral issues or knee instability.
These ranges illustrate ways to organize training. They are not an individual prescription. Adjust them for the exercise, your experience, and the rest of your program.
Heavier loads can be useful for developing maximum strength. The range shown is an example, and the load must match your current technique and capacity.
Muscle growth can occur across different loads and repetition ranges. This example is not a uniquely effective zone; your overall program and effort also matter.
This is an example of a longer set. A repetition target alone does not establish joint safety or whether the exercise is appropriate for you.
Example: For general fitness, start Terminal Knee Extension with 1-2 light, controlled sets and increase only when the movement remains comfortable. This is not rehabilitation dosage; use the frequency and progression given by your licensed healthcare professional for an injury or surgery.
Background for resistance exercises: the 2026 ACSM position stand covers healthy adults, and a load-comparison review found similar muscle growth across loads in studies using sets taken to muscular failure. These findings do not validate every exercise-specific range shown here or require training to failure.
This is one example of how Terminal Knee Extension could sit inside a complete workout. Your plan may use different movements after Ely checks your assessment.
